Recapping your question
Any recommendations where I should place these resources? [...]
I'm aware that I can place them in 'src/main/test/resources' [...]
I'm thinking more of resources for integration tests. Developers won't necessarily want to pull a 100's of megs of resources from version control for tests they likely won't run.

You might change to a multi-module project layout, something like:
multi-module project
|
|
+---+-----------------+
| |
source and unit test integration test
prj prj
then your developers could pull only source and unit test prj
.
Clearly integration test prj should have a compile scoped dependency on source and unit test prj
.
